SPECIFICATION forming part of Letters Patent No. 634,728, dated OctoberlO, 1899.

Application filed June '7, 1899. Serial No. 719,680. (No modeLl To all whom t may concern:

Be it known that; I, TAYLOR W. HEINTZEL Y grate which shall be readily and edectively operative by the reman while the engine is running and which shall be exempt from liability to permit the dropping of hot coals yor cinders upon the right of way or bridges on the line.

To this end my invention, generally stated, consists in the combination of an ash-pau body formed of one or more open-topped sections, each having a lower discharge-opening, valve-seats, each having one or more air-v supply openings and fixed to the sides of the body, air-valves, controlling the openings of the valveseats, and means for simultaneously actuating the air-valves.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings,- Figure l is a side viewin elevation of a locomotive ash.

pan, illustrating an application of my invention; Fig. 2, a partial plan or top view of the same,A the upper portion being broken away.

at the right-hand end of the figure to show the construction more clearly; Fig. 3, an end View as seen from the rear; and Fig. 4, a central section, on an enlarged scale, through one of the air-valves` and its seat.

My invention is herein shown as applied in 'connection with a locomotive ash-panof the construction for which Letters Patent of the United States No. 620, 7 O7 were granted and issued to me under date of March 7 ,1899; but it is not limited in application to that or any other specific form of locomotive ash-pan. The

body of the ash-pan is, as insaid Letters Patent, shown in the form of'three connected hopper-sections l 1 1, each of which is open at its top to receive solid matter which may be dropped from a fire-box, below which the ash-pan is located in the usual manner and is downwardly and inwardly tapered toward a discharge-openin g 2 at its lower end, around which is secured a guide-frame 3, in which a discharge-slide 6, which governs the disf y charge-opening, is fitted to traverse. The ash-pan is secured to the top rails of the engine-frame 14 or may be supported in any other suitableand preferred manner.

. In the practice ofmy present invention an air-supply opening 23 or a plurality of said openings are formed in the sides of the hoppersections l of the ash-pan, and the opening or openings ou each side are surrounded by a valve-seat 24, riveted or bolted to the side lplatevand having openings registering with the air-supply openings.- An air-valve 25 is fitted to traverse over and control each opening or set of openings, and the several airvalves on each side of the ash-pan are coupled one to the other by links or connectingrods 26, so as to be movable coincideutly to Wholly or partially cover or uncover the airsupply openings, as may be desired. The connecting-rods of the two sides are coupled at their ends bya cross-bar 27, to which any suitable mechanism for actuating the airy valves from a conveniently-accessible point, preferably the foot-plate of the engine, is counected. In the instance exemplified Opening and closing movement is coinoidently imparted to theentire set of airfvalves by means of a fluid-pressure cylinder 28, provided with a suitably-packed piston, the rod 29 of which is connected to the cross-bar 27. Air under pressure` orv steam is admitted to and exhausted from the opposite ends of the cylinder 28 through pipes 30 3l, controlled by a suitable four-Way operating cock or valve 32,

which is preferably located in the cab of the engine, so that the air-valves may be conveniently opened or closed by the fireman, as may from time to time be desired, while the engine is running. f

rlhe'air-valvesv 25 are herein shown as lof the oscillatory type, each valve controlling a Vset of four air-supply Openings and being journaled ou a pivot 33, secured in a central hub or boss in the valve-seat 24 and provided with a crank-arm 34, to which the connecting- IOO rod 2U is coupled.V It will, however, be'olovious that they may, Without departure from my invention, bettcd to reciprocate onV the valve-seats instead of oscillating thereon, and in ash-paus employed with comparatively Vdeep fire-boxes reciprocating valves may be found necessary to afford proper and suli cient area for the admission of air. againstV liability to setting 'lire to hridges or combustible material Von or adjoining the right of way by the escape of live coals or cinders from the ash-pan, the air-supply open- Y ings are covered by fire-guards formed of sheets of wire-nettingor perforated plate 35, which may beisecured in position by the bolts or rivets which connect the valve-seats to the ash-pan. Y

My invention has'been lfound of substantial advantage in practice in affording an easy and perfect regulation of the supply of air to locomotive-grates under the diferent conditions of service in and between the Working'of the engines on heavy mountain grades when loaded to their full tonnage rating and To guardV when descending grades or when the engine is running shut off. Y Y

II claim as my invention and desire to secu re by Letters Patent- V V l. In a locomotive ash-pain'the combina-V tion of a body formed of one or more opentoppedy sections, having inwardly-inclined side walls with air-supply openings therein, perforated fire-guards in said openings, and

air-valves controlling the passage of air there- Y through.

2. In a locomotve'ash-pan, thecombination f a body formed of one or more opentopped sections, having inwardly-inclined side walls With air-supply openings therein, perforated re-guards in saidV openings, Vairvalves controlling the passage of air therethrough, and mechanism operative fromV the foot-plate of the engine for actuating said valves.
